Transition pieces for dissimilar material pipes in high-temperature applications: Solutions for the process industry
Transition pieces, designed to bridge the gap between such dissimilar materials, are crucial to ensure system integrity and performance in these demanding environments. In this article, the authors explore a few transition piece usage situations and attempt to elucidate the challenges and approaches adopted.
The use of AI in process plant control: A proof of concept
The goal of this article is to highlight how: Supervised machine-learning and the Internet of Things can be used to develop a soft sensor that can enable the plant operator to continuously monitor product analysis, as well as gain insights into the root cause of off-spec product—in this work, the off-spec product is distillate. Also, this article will show how reinforcement learning can be used to train an AI agent to operate the plant.
Examination of design temperature allowance on creep range piping
This article delves into the effects of providing standard design temperature allowances for piping systems operating in the creep range. The aim of examining this practice is to enhance the understanding of its implications for pipe engineering.
Differential thermal expansion and welding problems in dissimilar joint of carbon steel to austenitic stainless-steel piping in high-temperature applications
Joining dissimilar piping materials has found widespread application in various process plant piping, most notably in jacketed piping with carbon-steel jackets and austenitic stainless-steel core piping with stainless-steel end closures that require welding to carbon-steel jacket piping.
